Reading/writing to remote database over the internet

Hi,
We have a hosted APEX application and have a requirement to be able to query and update our local database. I believe our options are:
- Set up some web services locally and reference them from our hosted APEX app
- Create a database link from the hosted instance to local instance and query/update the tables directly
I'm looking for opinions and advice on the best (secure, reliable) way to approach this.
Thanks,
Andrew.

Yes, put a servlet in between the applet and database. Let the servlet interace with the database on the applet's behalf and write that file on the server side.

  • Can you access an external HD plugged into the Airport Extreme from a remote location over the internet?

    Can you access an external HD plugged into the Airport Extreme from a remote location over the internet?
    Also can the content on the exteral HD plugged into the airport be accessed by the TV to stream content?

    The first question answer is yes..
    The question is asked continually.. please read the methods that Tesserax wrote up so well.
    See remote access tip here.

    Also can the content on the exteral HD plugged into the airport be accessed by the TV to stream content?
    Unlikely .. because your TV uses a system called DLNA.. and Apple do not support DLNA in any way shape or form.. because they are fully committed to iTunes.. Apple routers have no media extensions.. unlike most other decent brands now which mostly do support multimedia.
    Having said that.. you can place your video files on the external hard disk.. and play them.. but you need a player.. a real player not an apple TV which is a streamer.. eg A WD Live TV can play video files.. because it is a media player.. unlike your TV or apple TV.

  • I do not own neither a Mac nor an iOS devices. May I still be able to use all features of Time Capsule, including remote access over the internet?

    As described above.
    I do not own neither a Mac nor an iOS devices. May I still be able to use all features of Time Capsule, including remote access over the internet?

    You will have setup issues.. as the latest AC model requires a Mac or iOS device.. eventually apple will release a windows version of the utility.. and the current one does partly work but Apple seem in no hurry.
    You can find a Mac or iPad equipped friend to do the setup.. once setup the Windows computer can use it.
    BUTT you cannot access it from remote..
    Not with windows. You need BTMM and iCloud account. AFAIK even with those you cannot reach the TC.
    You can do it manually.. using a vpn. Buy a proper vpn router and use a vpn client on the windows computer.. the TC would be in bridge to the network..
    Apple really did not make this for windows.. and SMB access is only provided on LAN access not WAN.

  • Connecting to a database over the internet

    Hello ,
    Ok heres an interesting question -
    I would like to have an applet running on my browser which needs to connect to a central server over the internet, which in turn will need to connect to a database and query some results. These results will be stored as flat files within the server.
    At the moment, I have a URL that connects to the database via the
    internet and that is working. However I don't think my applet on my browser will be able to create a flat file on that server direclty.
    Could some one please tell me how to go about this problem?

  • Saving an Image to an Oracle Database over the Internet

    I would like to know how to transfer an image over the Internet and save that image to an Oracle Database. That is I am trying to make it so that a user can connect to the Internet and select an image file form their PC in TIFF, JPEG, or some other format. Next, I would like to save this image to an Oracle 7.3.4 Database in a LongRaw data type. This image will need to be save into a certain record in a table that I created. In the next few months we will be upgrading to Oracle 8 that uses Blob data type. Any one who knows how this can be done, please let me know.

    Yes, that's right. Here is the pertinent code:
    In the flax app:
    private function captureImg(imgEnc:IImageEncoder):void { 
    var ohSnap:ImageSnapshot;ohSnap = ImageSnapshot.captureImage(img, 0, imgEnc);
    textArea.text = ImageSnapshot.encodeImageAsBase64(ohSnap);
    InsertImage(textArea.text);
    In the HTTP service AS module:
    private  
    function InsertImage(sImageCoded:String):void { var sQry:String;sQry =  
    "INSERT INTO image (lImageId, blbBitMap, txtImage, lRecipeId) " sQry +=
    "VALUES(0, '" +sImageCoded +"', 'text', 23)"  
    //Alert.show(sQry);mysqlQuery(sQry,
    "InsertImage");}
    As mentioned previously, an HTTPrequest error is generated although I can enter
    the string into the blob manually in MySQL.

  • Remote Backup Over the Internet to Time Capsule

    I am looking to backup my macbook pro over the internet to a remote Time Capsule.  Is there a solution?  i'm using Lion OS

    How easy or hard this is depends on how the TC is setup, but if it is the main router and is getting the public IP from the modem it should be relatively easy to share on the internet. I haven't done it so let me leave that for you to google or others here to answer.
    Here is a pre-googled one for you to start.
    https://discussions.apple.com/thread/1792838?start=0&tstart=0
    You can do it manually using port forwarding from the router, if you are not using TC in router mode.
    http://gigaom.com/apple/access-your-time-capsule-over-the-internet/
    Note the requirements to use a public IP address (static address is far superior to do this) or dyndns address.
    Getting port forwarding to work in some routers is non-trivial.
    Apple should have designed the TC with secure ftp or some sort of vpn/ssl access.. but I digress. They didn't and as yet nobody has managed to hack one in.
    But I guess I would be trying to talk you out of doing it at all. Upload on vast majority of internet connections is slow.. even if you have fast downloads, uploads are usually restricted to 1mbit.. you might be fortunate and have really fast connection but mostly uploads are far to slow to want to do this.
    Lion will recognise that you are not on your home network, or the external backup device is absent and use local drive to take a snapshot.  Although a local hdd is obviously less safe than a true backup, it is generally an excellent solution for roadies. That is why it is turned on by default in notebooks.

  • Remote control over the Internet?

    Hi,
    I was under the impression that there was a way to use Zenworks to
    remote
    control via the Internet.
    I'm a consultant and support several NetWare 6 installations and would
    love to be able to use Zenworks to support my clients from here.
    The only way I have seen so far is either to remote control a
    workstation
    with something like PC Anywhere and run Console One remotely.
    Did I miss something?
    Is anyone doing this? How can I do this?
    Thanks
    Willem

    you're probably thinking of ZfD4.x, where you can remote control by
    just specifying the IP address.

  • Get an error message trying to access a remote PC over the internet on Mac

    At work we have a remote web work place. I can get into the site but when I try to access the link to the computer list the message below is displayed.

    With the new Snow Leopard it has support for the remote exchange server 2007. The one I'm desire to access would be XP Pro, but I'm not getting far enough to address them yet. When i use my PC there's a gold bar that comes down and says install Active X and I accept. Any idea's?

  • Remote printing over the internet

    My Time Capsule is in a storage room, connected to my cable modem.
    I have an Ethernet cable connecting the Time Capsule to my Airport Express in my home office. The Airport Express extends the network. My printer is plugged into the USB port on Airport Express, so I can print wirelessly.
    The Time Capsule supports MobileMe, which means when I'm away from home I can still connect to the Time Capsule's hard drive. I can even run Airport Utility remotely.
    What I can't do is print to my home printer. The Time Capsule supports printing to a printer connected directly to its USB port, but I can't figure out how to print remotely to the printer plugged into my Airport Express.
    Is this even possible? If I replaced the Express with an Airport Extreme, would that work?

  • Remote Access Over The Internet

    I have an iMac G5 in my home office setup, from which I am able to access the main server here at our business office. I can download files to my home computer, work on them, and upload them back to the server when I'm finished.
    How can I/do I set up my home computer for access in the opposite direction, in other words, to access files on my home computer from my office computer? Do I need any additional hardware or software?
    1Mac G5   Mac OS X (10.4.8)  

    Are you using any type of router at home? If not you don't need to do anything special except enable Personal File Sharing on your iMac G5.
    If you are using a router, you will need to configure the iMac G5 to use a static/manual IP address and then forward the appropriate ports through the router to your iMac G5.

  • P2V over the Internet

    Hi!
    We have an Exchange 2013 Server running on win 2012 Std on an physical machine. We need to have the backup for this as a VM on a remote site over the internet. What are the requirements and recommendations? We already have hyper-v servers on remote site.
    Thanks.

    Hi,
    Based on my research, here is a reference about the requirements of Exchange 2013 virtualization:
    http://technet.microsoft.com/en-us/library/jj619301(v=exchg.150).aspx#BKMK_Prereq
    We need to make sure we have enough RAM in the physical hosts for allocating memory for the VM we’ll create during the P2V migration, take care of enough free space on the disks for hosting the virtual hard drives and configure virtual networks.
    For more information, you can refer to the following documents:

  • Mirror or backup one Airport Time Capsule 2TB to another over the internet?

    Hello, is it possible to mirror, or backup, one Airport Time Capsule 2TB to another, at a remote location over the internet?
    Much appreciated.

    Copying a backup is actually a poor way to make reliable backups.. because an error creeps into the backup and the copy simply replicates it.
    I would use a USB drive plugged directly into the computer, and use a software like CCC to make a bootable clone.. I tell you honestly.. it is just wonderful when you have disk issue in a computer to be able to plug in a hard drive and boot the computer from it. Especially Macs with their hard to reach drives. Changing a drive on a PC laptop or desktop computer is usually trivial. It is far from trivial in a Mac. 
    Use two USB drives and swap them over to offsite weekly. Then use cloud for incremental in between.. or a combo of the TM .. TM can backup to multiple destinations.

  • Can the time machine be accessed remotely over the internet?

    Hi, I am thinking about purchasing the time machine. Can the hard drive on the time machine be accessed remotely over the internet?

    Do you realize that if you store some of your Mac's data (photos, music, etc.) ONLY  on the external Time Capsule, AND also  store your "Time Machine" app "system backups" on the Time Capsule,then if the Time Capsule hard drive ever fails you will have lost the " original" and the "backup" copies of all that data  (photos, music, etc.)?  They will be gone forever.  NOT recommended!
